Overview
The ICL7621DCPA is a dual operational amplifier from the ICL761X–ICL764X family, manufactured by Analog Devices Inc./Maxim Integrated. It features a monolithic CMOS design with ultra-low input bias current of 50 pA and low power consumption. The device operates on supply voltages ranging from ±1V to ±8V or single supplies from 2V to 16V. Key electrical parameters include a gain-bandwidth product of 44 kHz, a slew rate of 16 mV/us, and an input offset voltage of 15 mV. It is housed in an 8-pin PDIP package.
Feature Summary
- Ultra-low input bias current suitable for high-impedance circuits
- Wide supply voltage range supporting single or dual power sources
- CMOS output stage capable of swinging close to supply rails
Applications
- Long time constant integrators
- Picoammeters
- Low droop rate sample/hold amplifiers
- Battery-powered instruments
Procurement Notes
Verify the specific suffix 'DCPA' against official datasheets to confirm the PDIP-8 package and commercial temperature range. Ensure compatibility with existing PCB footprints and verify RoHS compliance status for the specific manufacturing batch before integration into final designs.
Selection Notes
Select this component when ultra-low input bias current is critical for signal integrity. It is appropriate for applications requiring wide dynamic supply ranges and low quiescent current. Compare performance metrics such as offset voltage and bandwidth against other members of the ICL761X series if higher speed or lower noise is required.
Part Context
This part belongs to the ICL761X–ICL764X family of monolithic CMOS operational amplifiers. The family combines low-power operation with pin-selectable quiescent currents. The ICL7621 variant specifically provides two independent amplifiers within a single compact package, maintaining industry-standard pinouts for easy replacement.
Replacement Considerations
Direct substitutes include ICL7621DCPA+ and ICL7621BCPA. Verify that alternative packages match the required mounting style and that thermal characteristics align with the application environment.
